Oso landslip costs

Unfortunately the toll from Saturday’s Oso landslip is rapidly mounting. Latest reports suggest that at least eight people have lost their lives and that up to 18 more might be missing in the debris. Unfortunately, the site remains very dangerous, such that substantial areas have yet to be entered. This will be the worst landslide in the USA for many years. The last event on a similar scale of which I am aware was the 25th December 2003 debris flow in San Bernadino County, California, which killed 16 people. It looks likely that this landslide will be worse.

Oso landslip resources

Whilst I am referring to this as the Oso landslip, in fact it is a reactivation of an existing landslide, known as the Hazel Landslide. This landslide is known to have moved 1988, and went through a second phase of movement in 2006. It is well described in a blog post from 2009 that can be found at: https://slidingthought.wordpress.com/tag/north-fork-of-stillaguamish/
